3,5" 4 TB 256 MB Serial ATA 6Gb/s Hard Drive - WD40EFAX (bulk)

Overview

The secret is in the technology

Specifically designed for 1 to 8 bay NAS systems, Western Digital Red hard drives are built to run 24/7, and are aimed at home and small office environments. These 3.5" hard drives are built around 64 to 256 MB of cache on a SATA III bus. They are compatible with most major NAS servers.

Western Digital's exclusive NASware technology , built into all WD Red hard drives, enhances the storage performance of NAS systems by eliminating common compatibility, integration, upgrade, reliability, and cost of ownership issues found in traditional desktop hard drives.

Designed for NAS

NASware optimizes power consumption to achieve significant energy savings and minimize hard drive operating temperatures. This improves overall drive reliability and performance and reduces the cost of ownership of your NAS system.

With intelligent error recovery commands , NASware prevents hard drives from being excluded from RAID through improved error recovery. This results in better availability and less time wasted rebuilding the RAID. With command completion for improved reliability, in the event of a power failure NASware minimises data corruption or loss by still executing the current command before shutting down.

    Mitigated

    I've got mixed feelings, out of the two I bought, one gave up on me in less than 2 years (~625h).

    A fairly blatant rise in bad sectors (and a click in my ear :D), which without ZFS parity would have corrupted my data. I'm also quite surprised by the SMR technology, I'd heard that performance could be degraded, and well it's true. For use with large files and for reading, it's fine, but for random writing, it's a disaster.

    However, my second one runs very well, without any errors or reallocated sectors.

    Short lifespan

    Less than 3 years before it gave up the ghost! I might as well buy a first-price product. Another thing that bothers me is that you have to use more than 100 characters to describe something that's mediocre.

    no problems for 2 years

    It's been running almost 24 hours a day without a hitch for the last 2 years.
    Rather quiet.
    100 characters is a lot to tell the life story of a hard drive though,

    HDD control

    This is the 1st time I've ordered from this site, the order was received on time, parcel in good condition. I have nothing to complain about.

    Good product

    The product works, it does its job. Despite the price having risen again.
    But received my parcel damaged torn, no anti-shock device in the box. I hope that in time the hard drive will hold.
